. RAILWAY-CROSSING GATE.

Application filed April 14, 1925. Serial No. 23,081.

provision of a railway crossing gate which 6 will be automatically movedinto an opera tive position by an approaching train and held in suchposition by the train while passing the crossing; the gate beingproperly weighted to cause it to return to its inopera- 19 tive positionafter the train has passed.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawingforming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 7 is a fragmentary transverse sectional view taken upon lineVIIVII of Fig. 2,

Figure 8 is a detail longitudinal sectional view taken upon lineVIIIVIII of Fig. 2, and

Figure 9 is a modified form of connecting mechanism by means of whichthe gate arms arranged onthe opposite sides of the track may be actuatedsimultaneously.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of this invention, the numeral 5 designates therailway track which is crossed at 6 ,by a road, or the like. Arranged onopposite sides of the track 5 at the roadway 6 are the posts 7, each ofwhich has a gate arm 8 pivoted thereto and weighted at 9 for causing thearms to normally be arranged in their inoperative positions. v p

The posts 7 have rotatably mounted thereupon iallb gilfOpvd pulleys10,11, 12 and 13, as indicated in the varidus fi ures. At dis randyspaced points along tlie track 5 are arranged the brackets let whichsupport the grooved trated. t I.

In Fig. 1 the ends 19 of a cable A are illus trated as being connectedtothe gate arms 8 on one side of the track illustrated. This cable extendsfrom the ends 19 downwardly and underneath the pulleys and 11 to extendas at 20 and 21 to the pulleys 17 and r 15 respectively where the saidcable passes over the pulleys just referred to and then back to andbeneath the pulleys 10 and 11 to its united or unbroken portion beneaththe pulleys 15, 16, 17 and 18, as illuscrossing 6, as indicated by thereference numerals 22 and 23, the cable at 23 passing beneath the pulley11 and downwardly under the guide pulley 24 while the cable at 22 passesunder the pulley 10; The portions 21 and 23 of the cable are fastenedtogether at 25 in close proximity to the pulley 15.

In Fig. 4 the cable A is illustrated as being fastened at 26 and 27 toopposite sides of the pulley 15. This pulley 15is illustrated in Figs. 1and 2'as having fastened thereon the normally vertically extending arm28. In Fig. 5 this arm 28 is illustrated as having been engaged by awiper member 29 carried by an approaching train, not illustrated, and.moved for causing thepulley 15 to be rotated to draw the cable, asillustrated. This drawing of one of the sides of the cable I will causeboth of the cable parts 21 and 23 to be pulled upon, dueto theconnection 25. This pulling uponboth ot' the cable parts 21 and 23 willcause the gate arms 8 to be moved into their operative or roadwayclosing positions.

It is to be understood that this arm 28 and pulley'15 are distantlyremoved from the gate arms 8, and, in View of this fact, after the lastcar carrying a wiper 29 has passed over the arm 28 and while the trainwould still be passing'the roadway 6, the gate arms 8 would be permittedto move into their inoperative or roadway opening positions. To overcomethis undesirable condition, the shaft 30 carrying the pulley 15 haskeyed thereto, see Figure 8, a grooved pulley 31 which has one end of acable 32 fastened thereto. This cable extends to the grooved pulley'34which is loosely mounted upon the shaft supporting the grooved pulley11. thereupon a normally vertically extending arm 36. It will new beseen thatdue to the engagement of the arm as by the mesa as This groovedpulley 34 has mounted carried by the train cars, the pulley 15 will beretained in its operated position even after the train'wipers havepassed over its arm 28.

In 3 the gate arms on the opposite side of the track are shown. Thesearms are connected to the ends 19 of a second cable B which extendsdownwardly to pass around the pulleys 12 and 13 and from them to thedistantly removed pulleys 1G and 18 which the cable passes around andreturns to and beneath the pulleys l2 and 13 to its united or unbrokenportion beneath the crossing 6. The parts of the cable in closeproximity to the pulley are connected together at 25 and are connectedat 26 and 27 to opposite sides of the pulley 18. It will now be seenthat by m'tating the pulley 18 by the arm 18 in either direction, cableportions will be pulled upon for moving the gate arms 8 into theirroadway closing or operative positions in the same manner and for thesame result as the above described arms 28 and 36 operate.

For the purpose of connecting the cables on too opposite sides of thetrack 5 for causing the actuation of one to actuate the other, thepulleys l7 and 18 have their supporting shafts provided with sprocketwheels 38 upon which ride the sprocket chains 39 which also travel overthe sprocket wheels -10 mounted upon the opposite ends of the singleshaft 11.

Fig. 9 is intended to illustrate the possibility of connecting thedistantly removed pulleys 15 and 16 by similar sprocket wheels 38,sprocket chains 39, shaft s1", and sprocket wheels 40.

It is to be understood that the forms of this invention herewith shownand described are to be taken as preferred examplesof the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing "from the spirit of the invention or thescope of the subjoine'd claims. c

Having thus described the invention, 1 claim 1. In a device of the typede'- ribed, the combination with a railway tr :h, of a pair of s )acedposts on each side of said track, a gate arm pivoted to each post, acable for each side of said track connected at its free ends to saidgate arms, means for inovab y supporting the intermediate portions ofsaid cables to permit the latter to extend to distant points along thetrack, and means adapted to be controlled by an approaching train formoving! said cables to cause the arms to be moved into their operativepositions.

2. In adevicc of the type described, the

con'ibination with a railway track, of a pair of spaced posts on eachside of said track, a gate arm pivoted to each post, a cable for eachside of said tracl: connected at its free ends to said gate arms, meansfor movably supporting said cables to permit the latter to extend todistant points along both sides of; the track, means adapted to becontrolled by an approaching train for moving; one off said cables tocause the arms con ected thereto to be moved into their o u;:-itivepositions, and means for operatively connecting; the second cable to thecable actuated by the train.

3. In a device 01" the type described, the combination with a railwaytrack, of; a pair of spaced posts on each side of said track, a gate armoivoted to each post, a cable for each side of said track connected atits tree ends to said gate arms, means tor movably supporting saidcables to permit the latter to extend to distant points along both sidesof the track, means for connecting; together ditlerent portions of eachcable so that movement of a cable will cause both of the free ends ofthe same to pull in the same direction upon the gate arms connectedthereto for moving both gate arms into their operative positions, meansadapted to be controlled ley an approaching train for moving said cablesto cause the arms to be moved into their operative positions, meansactuated by the train when passing the gate for causingthe arms toremain in their operative positions until the train has passed.

l. In a device of the type described, the combination with a railwaytrack, of a pair of spaced posts on each side of said track, a gate armpivoted to each post, a cable for each side of said track connected atits "free ends to said to arms, means for inovably supporting saidcables to permit the latter to extend to distant points along both sidesof the track, means to; connecting together difi 'erent portions (iteach cable so that movement oi a cable will cause both of the free endsof the same to pull in the same direction upon the gate arms connectedthereto for movi 5; both state arms into their operative positions, inans adapted to be controlled by an approach ng; train tor moving oneoi'f said cables to cause the arms connected thereto to be moved intotheir operative positions, means tor o 'icrativcly connecting the secondcable to the cable aclu ated by the train, and means actuated by thetrain while passing the gate {or causing: the arms to remain operativeuntil the train has passed.
